To all whom) it may concern:-

Be it known that I, EDWIN W. M. BAILEY,

a citizen of the United States, a resident of Amesbury, in the county of Essex and Commonwealth of Massachusetts, have invented an Improvement in Metal Window-Glass Cushions, of which the following is a speci fication. I

In the construction of closed bodies for automobiles, it is customary to provide the windows with vertically sliding glass plates which are guided at their side edges'by means of ways or channels secured in the casing, metal devices for this purpose being shown in my prior Patent #1,374,629.

While the devices therein shown are satisfactory for the purpose of guiding and holding the glass so that it will be protected against the shock of a. vehicle body,

- it has beenfound desirable to provide some cushioning means i'for'the top edge of the glass when in raised or closed position,

where the raising and lowering means are I applied to the lower-,end of the glass, as is customary, and theglass israised to'close the window opening. I

Prior to my" invention, when a cushioning. means has been employed forth'e upper edge of the glass, it has been found unsatisfactory, for several reasons, for example when rubber is employed, it loses its lifein about two years, while felt becomes worn and is liable to-beco'me torn or displaced, v

particularly where the edge. portion of the glass is forced between two felt surfaces.

It is desirable that-fa device for this purpose shall provide a. cushioning seat for the glass vertically, a cushioning support at each side thereof, and aconstruction which will permit the ready entrance of the glass between the lateral cushioning supports. into engagement with the cushioning seat. 1

The objects of my invention are to pro? vide a cushioning means for the upper edge portion of the glass which shall not only perform the functions above referred to, but which also may be made of metal at small expense, which will readily receive the end edge of the glass plate, even if the glass is somewhatim'perfectly guided at its side edges, which will provide a seat for said upper edge which will afi'ord a gradually increased resistance tothe closing movement and a resilient or yieldable abutment which will become operative at the end of such movement, so as to prevent undue strain on the closing means, and which, when the glass is in closed position, willeflective- 1y cushion the same laterally.

I accomplish these objects by providing a strip of resilient sheet metal which is'bent into an approximately U-form and has itsside portions provided with j "inwardly turned, convergently disposed cushioning end portions which are arranged to engage the end edge of the glass plate and be wedged "apart in advance of its reaching the highest point in its movement andto engage one or both more positively at the point at which the upward movement should be arrested. v

For a." more complete disclosure of my invention, reference is made to the, accompanyi'ng drawing in which:

Fig. I is a combined cross-sectional and perspective'view of a window casing, showing apreferred embodiment of my invent1on.) P

Fig. 2 is a longitudinal sectional view E; the form of cushioning device shown in Fig. 3 is a transverse section of the easing, showing the window glass in a lowered position, 11

Figs. 4, 5 and fi are sectional views of a V somewhafimodified form of the invention,

showing the parts diti'erent positions. H

In the drawing, the casing frame a is shown as provided with the usual side grooves in which metal guides 5, preferably such as are disclosed in my said prior patent, are arranged, which receive theside edge portions-of'theglass plates, and in which the latter'slides vertically, a similar groove being formed in the top of the window opening to (receive the top edge portion of the glass. ,7

According to my invention, I provide a strip of resilient sheet metelbent in ll-form to provide a bottom portion a? and two side portions 6 and f, which are bent at right angles to the bottom portion, so that said bottom andside portions tit against the bottom and sides respectively of the casing groove, in which the strip is secured, as shown. At or close to the outer edge of the groove, the side portions 6, f, are bent sharply inward at an angle of approximately 45, rorrning resilient endportionsg, it, which meet at a short distance from. the bottom portion a.

it 'liftingmiovement rapidly increasing until The'end portion 9 is provided with an out wardly turned lip'c' at its edge, forming a slight concavity on its outer surface into which the endportion It extends, so that its i-edge either enga es, or isheld in close prox- ,imity to the sur ace of said concavity, when the parts are in normal position, or the glass is lowered out of {dontactQtherewitm as shown in. Fig. 3. f"

I Whom-the glas's'z'i's raised, imdernormal conditionsgit will-be guided. so that its corners will engage theend portions e, f, practically simultaneously and then on further 11 ward movement the end portions e, 7, will be wedged apart-,the resistance to the the endfportioiii is, pushed aside and the top edge of the glass engagesth'edipddn the concave recess, at which point a yieldable abutment is provided which will indidate to the operator that the glass has been lifted to its fullest extent. The glass may be .forced up until the end of the lip z is the bottom and side shown 4. ll

moved into engagement with the bottom portion d, but usually the suddenly increased resistance will cause the operator to discontinue. raising the glass, so that undue strain will not be placed on the lifting means. In this position the end portions e, 7'' will not only resiliently enga e the opposite sides of the glass, so tha it will be effectively cushioned laterally, but they will also provide a yieldable resistance to the" f' and wedged them apart to an extent, as

shown in Fig. 5, providing a considerably increased resistances to the lifting of the glass andwthn if the glass is raised still imore; s'o that"it"'presses aside the end portion it will engage thelip i, which will provide a eatly increased resistance, or a slightly yieldable stop for the glass, as in dicated in Fig, 6

I claim':

1. In combination with a window casing having a window glass plate mounted to slide vertically therein, means to receive the upper edge of the glass, when raised to closed position, comprisin a. strip of resilient sheet metal bent in -form to provide abottom, two side portions and resilient end portions eiitending convergently from said side portions towards said bottom, to provide, a resilient support for the'glass at each side thereof, one of said end portions having its edge portion bent laterally towards the other to form a lip of less width than the thickness of the glass and arranged for engagement with the edge and adjacent side of the glass successively as it is moved to closed osition, to provide a yieldable abutmerit t ereforaa 2. In combination with a window basing having a window glass plate mounted to slide vertically therein, means to receive the upper edge of the glass, when raisedto "closed position, comprising a strip of resilient sheet metal bent in U-form to provide 1 a bottom, two side portions and resilient end portions extending convergently from said side portions towards said bottom, to provide a resilient support for the glass at each side thereof, said end portions each being bent laterally towards the other to form lips arranged for engagement with the edge of the glassto provide yieldable stops therefor as it is moved into engagement therewith.

3. In combination with a window casing havmg a window glass plate mounted to slide vertically therein, means to receive the upper edge of the glass when raised to closed position comprising a strip of resilient sheet metal bent in U-form to provide a bottom and two side portions, and rcsili:

'ent end portions extending convergently inward from said side port1ons to provide a resilient support for the glass at each side thereof, said end portions each having a laterally bent lip at its edge, said lips being arranged to overlap each other in position for successive engagement with the upper edge of the glass and to provide succcssively acting resilient abutments for the glass, as it is moved to lts closed position.

In testimony whereof I have signed my name to this specification.

EDWIN W. M. BAILEY.
